Sync v1.6.1

[TheEndless]

What's included

Highlights

Software Update

• A failed update check or download now shows a clear, friendly message instead of a raw HTTP error dump.
• Release notes render as formatted text in the dialog, rather than showing raw HTML tags.
• Polished the dialog's layout and font sizing, including the download-progress state.

macOS

• HDMI capture now works on packaged macOS builds: the signed app requests the camera and microphone access the capture feature needs.

Under the hood

• Updated Electron, CodeMirror, and js-yaml to the latest patch/minor releases.
• Pinned dependencies for reproducible builds.
